He had his first contacts with the extraterrestrial Sfath from Erra (Pleiades/Plejaren), from 1942 to 1953. Following contacts – from 1953 to 1964 – with Asket from the DAL Universe.

Since 1975 and until May 29, 2018, there have been 1898 personal and 1389 telepathic contacts with Pleiadian/Plejaren extraterrestrials and members of their Federation. The contacts are still on-going. 708 contacts are documented and available as contact reports.

The Pleiadians/Plejaren and their confederates are human beings with physical bodies and look very much like the people on Earth, with the exception of some minor anatomical differences, especially regarding the confederates. They live for 1,000 years, approximately. Their home planet — somewhat smaller than Earth — is called Erra. Its population is about 500 million people, while the entire federation has a population of 120 billion. The Pleiades/Plejaren are not identical with the Pleiades we can see on the night sky. They are 80 light-years beyond the Pleiades in another space and time constellation (= in another dimension). The Pleiadians'/Plejarens' consciousness ("spirit") and technology are much higher developed/advanced than here on Earth. The Pleiadians/Plejaren and the people on Earth have the same ancestors, but have developed separately, etc.

Hundreds of photos taken of beamships and their landing tracks, among other thingsPhotographs of 5 different variations of spacecraft, from 3.5 to 7 meter, usually piloted by humans. Other spacecraft and telemeter discs are remotely controlled and have also been photographed on several occasions. There also exist huge spaceships for traveling through space. There are photographs of single or multiple objects, day and night settings, above and below horizon line. There exist video and super 8 footage. Film analyzed by electron microscope, laser scanning and computer functions, thermogram edge identification, Z scale contour, density and film grain inspection, processed by electron microscope, microdensitometer, infraredometer, vidicon tube, digitizer, image process computer equipment.

Different segments of 8 mm motion picture filmThe films show variations in flight of ships; multiple craft appearances; instantaneous spatial translations by space craft; portions of the films have been analyzed in frame by frame format.

4 metal, 1 biological and 9 mineral and crystal samplesMetal analysis was described thoroughly in video tape format (Beamship the Metal). It showed that the metal was made by a cold fusion process. This technology is not yet known by terrestrial metallurgy.

A 20 minutes long sound recording of a beamship's whirring soundThe sound recordings of a non-shielded beamship was taken in the presence of several witnesses who heard the deafening noise, but weren't able to observe the ship that was screened from sight. The loud whirring sound could be heard for more than 4 kilometers as was confirmed by persons who soon arrived at the location. The scientific investigation showed that the sound is compromised of many tones/frequencies with unusual anomalies and rapid changes in tone and frequencies.

Landing tracksDepending on the type of beamship there could be seen 1 or 3 landing tracks. When three, they were 120 degrees apart, circular; grass was depressed in counterclockwise rotational direction, visible for months after landing occurred. Both existing and new grass were affected.

WitnessesAdditional to "Billy" Eduard A. Meier there exist more than 120 persons who have witnessed evidence regarding the Pleiadians/Plejaren, their beamships, or BEAM.

On the 3rd February 2017, on Billy’s 80th birthday, a meeting and small celebration was held on Quetzal’s estate (on Erra), during/at which all those contact persons were present who, until then, had made an apperance.​
